The application discloses a long spiral drilling machine concrete automatic pouring control method and system, the method comprises the following steps: in response to the pipeline filling rate and / or the concrete pressure reaching the preset value, the drill pipe automatic lifting mode is started; according to the feedforward speed and the feedback correction amount generated based on the concrete pressure deviation, the lifting speed is calculated, the winch equipment is controlled to lift the drill pipe according to the lifting speed, and the real-time correction of the lifting speed is carried out in the lifting process; the total lifting length is divided into multiple preset lengths, when the drill pipe is lifted by the preset length each time, the pile filling rate in the preset length range is calculated, if the pile filling rate is lower than the preset filling rate, the underfilling backfilling is carried out, after the backfilling is completed, the drill pipe returns to the original position and continues to lift until the concrete pouring is completed. The pouring process of the concrete is changed from the experience type manual adjustment to the closed loop control based on the pile filling rate and / or the concrete pressure, the underfilling and overfilling phenomena are avoided, and the piling quality is higher and more stable.

This invention provides a high-efficiency, low-temperature-rise passive harmonic filter, belonging to the field of filters. It includes a main base housing and a top housing with evenly spaced heat dissipation side slots on both sides, which work in conjunction with symmetrically fixed cooling fans on the inner side to form an effective airflow channel. The cooling fans draw external cool air into the top housing, accelerating airflow and allowing heat to be quickly dissipated to the external environment, significantly improving heat dissipation efficiency. The evenly fixed heat dissipation side plates on the outer side of the passive harmonic filter further increase the heat dissipation area, while the porous structure of the perforated support plate also facilitates airflow and enhances the heat dissipation effect. Through these heat dissipation designs, the temperature rise of the filter during operation is effectively reduced, ensuring that the internal electronic components operate in a suitable temperature environment, improving component performance and lifespan, reducing the failure rate caused by overheating, and improving the reliability and stability of the filter.
